Yeah, that's actually how the gaming industry works. You see, different companies make a bunch of different games, because fans don't all have the same tastes.
Just focus on the games you like and ignore the ones you don't.

You might want to walk into a game store sometime and look at the Wii U shelf. Yeah, Nintendo definitely has a lot of beloved iconic series, like Mario, LoZ and so forth, but if you're only going to focus on them, and completely disregard games like Assassin's Creed III, Batman, Bayonetta, Mass Effect, ZombiU, Monster Hunter and even CoD (if that's what you prefer), then obviously you're going to have a very biased and uneducated opinion.
